I GAS-HEATED RADIATOR.

Application filed March 12, 1923. serial no. ceases.

To [1. whom it may concern:

Be it known that I, GEORGE P. SCHMITT, a citizen of the United States,residing at Oakland, in the county of Alameda and State of California,have invented certain new and useful Improvements in Gas- HeatedRadiators, of which the following is a specification.

This invention relates in general to heating stoves, and in particularto stoves of the gas-radiator type in which the source of heat isgaseous fuel, the hot gases circulating through the radiator for warmingthe surrounding air by direct radiation.

An object of the invention is to 'produce a radiator of the above type,in which the combustion is effected within the radiator and near the topthereof, and the resulting hot air and gases caused to pass downwardthrough one side of the radiating unit and up through the other side.

A further object is to provide such a radiator with a preheating chamberfor warming the incoming air to the same.

Another object is to produce such a radiator in which the hot air andgases are superheated just before being discharged from the radiator.

And still another object is to provide such a radiator with a damper toshunt hot gases immediately to the discharge fine, to dry out and heatthe latter for the promotion of an immediate and effective induceddraft. This latter object is of great importance in cli-' mates wherethere is considerable moisture in the air, as the vent pipe to'theatmosphere will not draw effectively unless it is thoroughly dry andfree from moisture.

With the above and other objects in view, the means by which I securethe efiiciency of my invention will be fully set forth in thedescription and drawings of that embodi ment of my invention which Ihave selected for illustration, and which is the best as yet devised byme.

In the accompanying two sheets of'drawin s:

igure 1 is a side elevation of a five-loop radiator constructedaccording to my in vention.

Figure 2 is an end elevation of the same.

Figure 3 is a vertical longitudinal section taken on the line A-A ofFig. 2.

Figure 4 is an enlarged fragmentary section of one of the filler loops.

1' Figure 5 is a similar section of the middle Referrinlg to thedrawings and the figures thereof:- have illustrated a five-loopradiator, though a greater or lesser number of loops may be usedaccording to the space to be warmed. Each loop of the series is atelvbelow the superheater which constitutes the combustion chamber.Otherwise the individual loop units are separate or insulated from eachother and fitted together in cement in any suitable way, such as bycommon male and female joints as shown.

Near the top of each loop is its fire box 3. The fire boxes are opentoward each other so as to make a. continuous fire box from end to endof the radiator, closed at the ends by the walls 4 and 5, in one ofwhich ast, is a mica covered peep hole 6, and in the other of which is adoor and hole 7 throughjwhich the gas may be lighted. In the lower partof the fire box, innnediatel below the peephole 6 and the lighting ho e7 is the burner 8, which may be in the usual form of a perforated pipeas shown.

The lower half of the fire box is the preheating chamber and is open tothe circumambient air, which air, when the burner is lighted, rises andmixes with the gases of combustion. The mixed hot air and gases, risingagainst the top 9 of the fire box are reflected and pass over thebaffle-Wall 10, and down to the bottom of the loop in the le 11 thereof,and thence up in the other leg 1% and into the superheating chamber 1 2.

In the superheater the gases are further heated by the top 9 of the firechamber and take a lateral and spiral courseto the mlddle loop 18 andpass out at the flue 13. The effect of superheating is to vaporizeentrained moisture, reheat the spent gases and increase the draft.

In the middle loop 18 of the series, l preferably make an opening fromthe fire box till tlti

that in starting the operation of the radiilw ator the hot air andproducts of combustion,

may pass directly to the flue 13, thus startmade somewhat higheropposite the opening 14, as seen inv Fig. 5 to cause an increased drafteffect when the damper is. opened. i In operation, the issuing gas islighted and damper opened as shown by'the dot and dash lines in Fig. v5,to create an immediate draft as previously explained. In the interim,the flame of the burner impinging upon the sidewalls of the continuousfire box, has caused the said walls'to become hot, thus starting thepreheater to function efficiently. A

The damper is then closed and complete circulation effected. The coldair is drawn into the preheater and heated by the walls thereof beforethe said air passes through the flame. The hot air and gases in theseparate loops complete little more than a fullcircuit, as shown by thedot and dash arrows, and collect in the superheater and are again heatedby the flame impinging on i the division wall 9, thence the horizontalcolumn of moving products of combustion pass to and through the vent/13to the at mosphere.

It will be observed that the' radiator when in use, not only heats theroom but'causes Y a constant ventilation of the same aswell.

From the foregoing description taken in connection with the accompanyingdrawings, the advantages of the construction and method of operationwill be readily understood by those skilled in the art to which theinvention appertains, and while I have described the principle ofoperation, .together with the device which I now consider to be the bestembodiment thereof, I desire to have it understood that the device shownis merely illustrative and that such changes may be made when desired,as fall within the scope of the appended claims.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. In a stove of the gas-radiator type, a

radiating unit having a fire box near the top thereof and a superheatingchamber above said fire box, the. chamber being open for circulation.

2. In a stove of the gas-radiator type, a radiating unit having a.burner, fire box and discharge flue near the top thereofand having anopenin from said fire box direct to the discharge ue, and a damperadapted to close the said opening.

3. A stove of the gas-radiator type composed of separate radiating unitsconnected .together, and each unit having a fire box near the topthereof, with an open bottom, the said bottoms forming one continuousopening to the atmosphere.

i 4. A stove of the gas-radiator type composed 'of separate radiatingunits connected together, and each "unit having a tire box near the topthereof, and a superheating chamber immediately above said fire box, thesaid fire boxes opening into each other to form a continuous fire boxand the said superheating chambers opening into each other to form acontinuous superheating chamber. 4 e

7 A stove of the gas-radiator type, comprising a burner, a combustionchamber, a

superheating chamber, apreheating chamber and circulating tubes leadingfrom the combustion chamber to the superheating chamber, the latterprovided with an outlet for the products of combustion, the burner beingpositioned in the preheating chamber and whichlatter also'forms the airinlet, the combustion chamber being positioned between the preheatingand superheating chambers, and the latterchamber being the uppermostpart of the stove.

Intestimony whereof I 'afiix my signature.

GEORGE P. SCHMITT.
